Answer:
BC = 6.8
Step-by-step explanation:
The distance from A to B, then from B to C, is the same distance as from A to C.
Thus,
AB + BC = AC
AB = 8x + 8
BC = 4x + 2
AC = 22
AB + BC = AC
(8x + 8) + (4x + 2) = 22
Expanding the parenthesis:
8x + 8 + 4x + 2 = 22
8x + 4x + 8 + 2 = 22
12x + 12 = 22
Subtracting 12 from both sides:
12x = 10
Dividing both sides by 12:
x = 10/12 = 1.2
x = 1.2
We're looking for BC. As we know,
BC = 4x + 2
Let's now put in x = 1.2 into this equation:
BC = 4x + 2
BC = 4 * 1.2 + 2
Since 4 * 1.2 is 4.8:
BC = 4.8 + 2
BC = 6.8
Answer: BC = 6.8
Answer:
3
Step-by-step explanation:
to find side length of squares take square root of areas
first square side length: 9
second square side length: 6
difference between 9 and 6 is subtraction, 9-6=3
The first relation is a function, the others no
Answer:
<u>y ≤ 4</u>
Step-by-step explanation:
Solving :
- Highest y-value is 4
- The other y-values are less than 4
- Hence, the range is : <u>y ≤ 4</u>
